We report new percutaneous techniques for perforating the pulmonary valve in pulmonary atresia with intact ventricular septum, in 3 newborns who had this birth defect. There was mild to moderate hypoplastic right ventricle, a patent infundibulum, and no coronary-cavitary communications. We succeeded in all cases, and no complications related to the procedure occurred. The new coaxial radiofrequ...

Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles). BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to...

Two patients with pulmonary atresia and ventricular septal defect underwent implantation of the diminutive pulmonary arteries on the ascending aorta by interposition of short segment of azygos and innominate veins. The very thin structure of the systemic veins' wall matched perfectly the fragile pulmonary arterial wall. The anastomosis were perfectly patent and no aneurism dilatation was eviden...

Definition of “functionally single ventricle” includes a wide spectrum of anatomical variants such as double inlet left or right ventricle, mitral or tricuspid atresia, unbalanced atrioventricular canal, heterotaxy syndrome with one normally developed ventricle or other congenital heart defects with severe hypoplasia of one of the ventricles [2]. Anatomical and hemodynamic abnormalities in thes...

Neonates with pulmonary atresia and intact interventricular septum (PAIVS) do not have pulmonary vascular disease secondary to their heart abnormality. Persistent pulmonary hypertension of the newborn has not been described in association with this condition. The case is reported of a female neonate born with PAIVS, who preoperatively had no clinical evidence or any risk factors for persistent ...

The diagnosis of primary pulmonary vein stenosis is often overlooked because its symptoms overlap lung diseases and pulmonary arterial hypertension. Its diagnosis may be difficult because the condition is progressive and associated with other defects. We present a case of pulmonary vein stenosis in a newborn with stenosis of the left-sided common pulmonary vein, diffuse hypoplasia of the superi...
